Excess Break-Away Cable Length?

When I connected things up the first time on my own, I found the breakaway cable was nearly dragging on the ground. I'd rather not have it snag on something, so I used a binder clip (normally used to hold documents together) to "shorten" the cable a bit but still allowing it room to move on turns. Does anyone have a better idea, or am I routing the cable wrong? (it goes from the breakaway device under everything to a hook on my bumper)
